Multivitamins
A multivitamin is the "just in case" of the supplement world, and for a lot of people that is exactly what it is. If your diet is genuinely varied you may not need one at all, but plenty of us fall short somewhere, and a daily multi is a cheap bit of insurance. We rank by real ratings and review volume, and lean towards the well-established brands rather than whatever launched last week.
Common questions
Do I actually need a multivitamin?
If you eat a broad, balanced diet, possibly not. They are most useful if you are a fussy eater, on a restricted diet, pregnant or older, when getting everything from food gets harder. When in doubt, a GP or pharmacist can point you at the specific thing you are short on rather than a catch-all.
Men's, women's or one-a-day, does it matter?
The gendered versions mostly tweak iron and a few dose levels. They are fine, but do not overthink it. A reputable one-a-day covers the basics for most adults.
